...
channel : indicates the category of channels included in the analysis: MEG or EEG
example: cfg.channel = {'EEG'};
latency : indicates the time window to use for the analysis
By default: cfg.latency = 'all'
clusteralpha : initial alpha threshold, used to form the clusters
By default : cfg.clusteralpha = 0.05;
minnbchan
minnbchan : min number of adjacent channels required to consider they form a cluster
By default: cfg.minnbchan = 2;
tail
cfg.tail = 1;
clustertail
cfg.clustertail = 1;
alpha : significance threshold for the cluster's statistics
cfg.alpha = 0.05;
numrandomization
cfg.numrandomization=1000;
